ATP International Series Gold
International Series Gold was a series of professional tennis tournaments held internationally that were part of the ATP Tour. The tournaments were positioned below the ATP Masters Series, and above the ATP International Series in terms of prize money and ranking points available.
International Series Gold tournaments offered players cash prizes and the ability to earn ATP ranking points. See Association of Tennis Professionals#Rankings for more details.
Effective in 2009, this series of tournaments became the ATP Tour 500, incorporating many of the same tournaments. The "500" represents the number of ATP ranking points earned by the winner of each event in the series.
